Status: ModifiedMedium (4.6)—

Unchecked error condition in LoginWindow in Apple Mac OS X 10.4 through 10.4.7 prevents Kerberos tickets from being destroyed if a user does not successfully log on to a network account from the login window, which might allow later users to gain access to the original user's Kerberos tickets.
